Where do I find a decision tree analysis add-in? If there are more than
one, which one would you suggest I use? <

For sequential decision problems under uncertainty, i.e., linked decisions,
try TreePlan (www.treeplan.com), Lumenaut (www.lumenaut.com), PrecisionTree
(www.palisade.com), ...

My favorite is TreePlan, since I wrote it.

For others, or for classification trees used in computer science, search
Google.
